You would have to create an ALTERNATE POSITION VIEW in your assembly drawing. You need to create a configuration within your assembly model that would have only those parts visible that you want to create the phantom parts in your drawing. I normally call that configuration ALT POS VIEW but you can call it whatever you would need to. Then in your assembly drawing view you create an ALT POS VIEW & select the configuration that you created for it. The one drawback to this is if you have a BREAK OUT section in that view, then Solidworks will not allow you to create an ALTERNATE POSITION VIEW in that drawing view for whatever dumb reason.

One way would to create Display States that capture the look you need, where the components in the background could be a different color, which you could pick a color that would almost blend in with the drawing sheet color......
